SGP/MMCR/C1 - Lost Spectral data
DataStreams:sgpmmcrspecmomC1.a0
Description:
A mistake in my code to generate md5 companion files and rename the raw MMCR spectra files 
to ARM convention resulted in the loss of the spectra files.  I've tried recovering it 
with several disk recovery programs but to no avail.

SGP/MMCR/C1 - Missing or corrupt spectral data files
DataStreams:sgpmmcrspecmomC1.a0
Description:
Some or all of the SGP.C1 MMCR spectral data archived during this time period were 
corrupted due to problems with the media used to transfer the data.  Known corrupt files have 
been removed from the ARM Archive but users should be aware that additional corrupt data 
files may still be accessible.

Note: If you identify corrupt data files, please contact the ARM Archive at 
armarchive@ornl.gov or 865-241-4851.
